Definitions

  • the invention relates to a paper web separating and holding device for preventing printing unit damage in the event of paper web tears or folder damage in the event of malfunction reports.
  • a separating device in which a paper web is passed through a slot of a rotatably mounted shaft without contact.
  • a stationary cutting knife is placed with its cutting edge close to the surface of the slotted shaft.
  • the separation device receives a signal via a control device.
  • the slotted shaft is rotated by 90 ° by means of a pretensioned torsion spring, the paper web being sheared off by the cutting knife. At the same time, the path to the subsequent processing station is blocked.
  • a disadvantage of the separating device according to DE-OS 31 42 089 is that the new paper web beginning created by the paper web separation is not held. In addition, there is a considerable risk of injury due to the cutting knife provided.
  • a paper web catching device which clamps a paper web in the event of a web break between two driven rollers and drives it at machine speed. A separation or holding of the paper web is with the object according to DE-AS 21 56 505 not possible.
  • the invention has for its object to provide a paper web separation device in a web-fed rotary printing press, which holds a beginning of the trailing paper web strand.
  • the invention is achieved according to the invention by the characterizing part of claim 1.
  • the advantage of the invention is in particular that a beginning of a paper web of a subsequent, separated paper web strand is held so that it can be found quickly, so that the paper web can be quickly re-threaded. This can significantly reduce downtimes of the web-fed rotary printing press. A sufficiently large clamping surface as a result of the clamping process ensures that the beginning of the paper web is gripped securely.
  • a web-fed rotary printing press 1 has a separating and holding device 4 for a paper web 6 in front of printing units 2 and folder 3.
  • the separating and holding device 4 is arranged axially parallel to printing nips 9, which are formed by cylinders 11, 12 of the printing units 2, and fastened to side frames 7, 8 of the rotary printing press 1.
  • the separating and holding device 4 has a base plate 13, 14 at its ends fastened to the side frames 7, 8.
  • a cross member 16 with a U-profile is arranged horizontally and fastened to the base plates 13, 14.
  • An opening 17 of the cross member 16 has an opening 18 of a U-profile strip 19, which is arranged at a distance a (approx. 10 to 16 mm) from the cross member 16.
  • the bar 19 is slidably mounted on two guide pins 21,22.
  • the strip 19 each has an elongated hole 46; 47, through which the guide bolts 21, 22 pass with a small amount of play in the vertical direction and with a lot of play in the horizontal direction.
  • the elongated holes 46.47 prevent the bar 19 from tilting on the guide bolts 21, 22.
  • the guide pins 21, 22 are each provided in the vicinity of the side frames 7, 8, with one end each being fastened (e.g. screwed or fitted) to a support 23, 24, which is fixed at right angles to the base plate 13, 14.
  • Two working cylinders 26, 27, likewise arranged on the supports 23, 24, parallel to the guide bolts 21, 22, with pistons 28, 29 that can be pressurized apply the force to move the bar 19 on the guide bolts 21, 22.
  • the pistons 28, 29 each have a piston rod 31, 32, the end of which is attached to the bar 19.
  • a slightly elastically deformable clamping body 33, 34 (e.g. rubber tube) is provided in the openings 17, 18 of the cross member 16 or bar 19, which extends over the entire width of the rotary printing press 1 and is somewhat wider than the paper web 6.
  • the clamping bodies 33, 34 are clamped in each case by means of a clamping strip 36, 37 on the stationary cross member 16 or movable strip 19.
  • the terminal strips 36, 37 have a number of threaded bores 38, 39 at intervals.
  • Fastening screws 41, 42 provided for fastening the clamping bodies 33, 34 each protrude from the outside through bores 43, 44 in the cross member 16 or 19 and the clamping bodies 33; 34 through and open into the threaded bore 38; 39.
  • the working cylinders 26, 27 each have a compression spring 48, 49, which are each arranged around the piston rods 31, 32, with a first end being supported on the piston 28, 29 and a second end on a piston stop 51, 52.
  • the working spaces 53, 54 of the working cylinders 26, 27 are connected to a pressure medium source 59 (e.g. pneumatic or hydraulic unit) by means of a common pressure line 56 via an electromagnetic valve 58.
  • the solenoid valve 58 is connected to a control device 61 by means of a control line 57.
  • the control devices 61 corresponding to the separating or holding device 4 e.g. buttons, photodiodes, sensors or the like) are always arranged behind the respective printing unit 2 or in the folder 3.
  • a malfunction of the paper transport e.g. web break in the printing unit or missing copy in the folding unit
  • the solenoid valve 58 switches and releases the connecting line 56 between the pressure medium source 59 and the working cylinders 26, 27. Due to the pressurization, the pistons 28, 29 extend simultaneously and move the bar 19 with the clamping body 34 on the guide pin 21, 22 in the direction of the clamping body 33, the compression springs 48, 49 being tensioned.
  • the web separation takes place at the moment of contact (high coefficient of friction, e.g. rubber) of the two clamping bodies 33, 34.
  • the invention is not intended to be limited to the exemplary embodiment shown. So it is of course also possible to adjust the clamping body against each other by pivoting.
